1 'Claim. CI. 50-51 This invention relates to an eave construction particularly adaptable/for use in a building of the construction as shown and described in my co-pending application Serial No. 445,545, new Patent No. 2,832,445, entitled Demountable Metal Building Structure.

The invention involves the application of one element of the box return on a roofing element and the other element on a side wall panel, the two elements coming into overlapping relationship upon moving the roofing panels into positions.

The primary purpose of the invention is to provide a neat enclosure between the roofing panels and the wall panels to give a pleasing appearance, but most importantliy to enclose the space therebetween to form a substantially airtight juncture between the roof and the side wall.

A further primary object of the invention is to provide a box return which requires no further operations in the assembly on the job other than to shift the roofing panel into its final position on the roof, all without the use of screws, bolts, or welding operations.

These and many other objects and advantages of the invention will become apparent to those versed in the art in the following description of one particular form of the invention as illustrated in the accompanying drawing, in which Fig. 1 is a view in side elevation of a fragmentary part of a building structure to which the invention is applied;

Fig. 2 is a transverse section on the line 2-2 in Fig. 1;

Fig. 3 is a detail in perspective of the upper end portion of a side wall panel;

Fig. 4 is a view in end elevation of a roof panel; and

Fig. 5 is a view in top perspective of the upper end of i a building structure member.

A plurality of spaced apart, vertically disposed posts are set up and these posts are in line to define a side wall. These posts 10 support a roof frame structure comprising a'plurality of rafter members 11 spaced apart a distance equal to the spacing apart of the posts 10. The rafter members 11 are tied together by a crossbar 12 which rests in each instance upon the top ends of the posts 10. The rafter members 11 and the posts 10 are identical in cross-sectional shape, as indicated 'in Fig. 5 wherein there is a channel formed to have a web 13 from the sides of which extend legs 14 and 15; face members 16 and 17 turned respectively from the outer ends of the legs 14 and 15 in parallel relation to the web 13; inturned flanges 18 and 19 extending at substantially right angles to the faces 16 and 17 inwardly toward the web1'3 and in spaced apart relation; and terminal feet '20 and 21 turned at right angles from the inner edges of the flanges 18 and 19, directed toward the legs14 and 15 respectively, and finally terminating in flanges 22 and 23 turned toward the face members 16 and 17, in spaced relation between the flanges 18 and 19, and the legs 14 and 15 respectively. The gap between the two flanges 18 and 19 is suflicientl-y wide to form in effect a slot receiving therein flanges 24 and 25 turned at right angles from the wall panel 26, Fig.

- 2 r 3. The wall panel '26 has a width to present the flanges 24 and 25 within the slot generally indicated by the numeral 27 of each of the posts 10. The panel 26 in each instance is maintained in abutment with the faces 16 and 17 of each of the posts 10 by suitable latch means, it being understood that the construction herein shown and described is employed in a demountable type of building so thatthcse panels may be released from engagement with the posts 10.

The means for retaining the panels 26 in engagement with the posts 10 constitute one or more bars 28 extending across the inside of each panel 26, so that the ends thereof come into close proximity with the respective legs of the posts 10. This bar 28 is preferably hollow, and may be attached to the panel 26 by any suitable means, such as by spot welding thereto. On each end of the bar 28 is mounted in a rotatable manner a latching member 29 which may be rotated to lap over the inside of the post 10 in each instance, that is over the web 13. These latches 29 are formed to draw the panels against the faces 16 and 17 of the post 10 with the flanges 24 and 25 entering the slot 27.

The upper end of each of the panels 26 is provided with an outwardly turned flange 30 having a length equal to the width of the panel 26 and extends under and against the members 11, substantially half way thereacross.

adjacent to the opposing legs of adjacent rafter members bcrs 11 with its flanges '34 and 35 entered into the slots 11, and spacing the latch members 29 outwardly from the underside of each panel 33 so that they may be :0- tated to engage across the underside of the rafter member in each instance.

The underside of the roof panel 33 in each instance has fixed thereto a downwardly extending fascia 37, and from the lower end of the fascia 37 there extends inwardly substantially at right angles to the fascia a flat panel 38.

This member 37 drops vertically below the roof panel 33 to carry the return panel 38 compressibly against the underside of the flange 30. The height of the fascia member 37 is such that it urges the flange 30 against the underside of members 11 by the engagement of the panel 38 thereunder. The length of the fascia 37 is substantially equal to the distance between the opposing legs of adjacent members 11.

In this manner, an interconnection is made between the roof panel 33 and the wall panel 26 completely en closing this space between it and the roof panel 33 between and across under the members 11.

In order to bring the panel 38 under the flange 30, the roof panel 33 is laid across the tops of adjacent mem- 27, and then the panel 33 is moved upwardly along the rafter members 11 to bring the panel 38 from some suchposition as indicated 'by the dash lines in Fig. 2, up under the flange 30. In this position of the roof panel 33, an upwardly turned flange 31 at the then upper end of the panel 33comes to the upper end of the rafter 11 or approximately at that end. The panel 33a coming up the rafter 11a from the other side of the roof likewise has a flange 31a. The panels 33 areretained in position against sliding down the rafters -,11 by means of a slotted tube 32 entered from sides of the'panels 33,

and moved thereacross to have the flanges 31 and 31a confined within the tube 32 as indicated in Fig. 2. This tube 32 thus maintains the panels 33 in their uppermost positions along the members 11 and at the same time maintains the compressive engagement between the panel 38 and the flange 30.

The structure is demounted by reversing the assembly to remove the tube 32 first, release the latches 29, pulling the roof panel 33 downwardly in each instance to carry the panel 33 away from the underside of the flange 30 whereupon the panel 33 in each instance may be lifted from their supporting rafters 11. Then the wall panels 26 may be removed by releasing the latches 29 from engagement with the supporting posts 10.

While I have herein shown my invention in the one specific form, it is obvious that structural changes may 'be employed without departing from the spirit of the invention, and I therefore do not desire to be limited to that precise form beyond the limitations which may be imposed by the following claim.

I claim:

In a building structure, a side Wall comprising a side panel; a flange outturned from the top end of said panel at substantially a right angle thereto; an inclined roof frame sloping upwardly from said side wall; a roof panel slidable up and down said roof frame; a member L- shaped in cross-section and fixed to and depending from a lower end portion of the roof panel, said member comprising a face downwardly extending from the roof panel a distance to a lower edge portion and a second face turned approximately horizontally from said first face toward said side wall panel; said horizontal face being cam'ed toward and below and engaging under said flange upon moving the roof panel up said roof frame; said flange being spaced below said roof panel a distance corresponding to the height of said member first face, the two faces of said member defining an eave closed box trim with said flange bearing on the said face thereof; the free interengaging of said second face with said flange retaining said roof panel lower end portion on said roof frame.
